本発明は、放射−を検出することにより擬似乱数を発生
させる方法に関する4のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for generating pseudorandom numbers by detecting radiation.
一般に、Il偏乱数を発生させるには、会同法などによ

ている。Generally, in order to generate Il random numbers, pseudo-random numbers are generated by performing calculations using a computer, such as by using a computer method.
このように計算機を用い九演算による場合は、演算に用
いる初期値、係数の値によっては、周期性、偏りなどの
点で十分な乱数が得られなくなるという問題がある。In this way, when a calculator is used to perform nine calculations, there is a problem that, depending on the initial values and coefficient values used in the calculation, sufficient random numbers cannot be obtained in terms of periodicity, bias, etc.
本発明は前記問題点を解消するものて周期の長い、偏9

It provides a method to generate small pseudo-random numbers of T
(o) A device characterized in that radiation emitted from a radioactive substance is detected by a semiconductor element integrated device, and pseudo-random numbers are generated by detecting the position of the element that has changed (by the radiation). Out.
以下、本発明の実施伺を図面によって詳細に説明する。Hereinafter, implementation of the present invention will be explained in detail with reference to the drawings.
図は、本発明の一実施例を示す構成図で6る。Figure 6 is a configuration diagram showing one embodiment of the present invention.

Mのビットt%01に設定しておくと、アルファ線20
進入し九ビットのみが%11の状態になる。100ナノ
秒の間にはおよそ1つのビットが111の状態になる。In other words, the alpha mass 2 emitted from the radioactive element 9 oran 1 in 1 liter is converted into the radioactive element uranium 1 to 10a.
44000 bits R with 1m11 area and 10-
Enter into AM101 bit. At first, all B people M
If bit t%01 of M is set, alpha rays 20
Only 9 bits enter the state of %11. Approximately one bit is in the 111 state during 100 nanoseconds.
アルファ纏2は等方的に放射される良め、どのビットが

生する。The alpha band 2 is emitted isotropically, and which bit becomes the %11 state is completely random. Every 100 nanoseconds, the decoder 4 detects the address of the bit at %1# and outputs the address number 489991 from t, , o. %Ol all bits of 几AM3 again
By repeating the above operation with the setting set to , a pseudorandom number u5 ranging from 0 to 659991 is generated every 100 nanoseconds.
以上の説明において、説明を具体化するために放射性物
